CDMA Diamond data connection problem?

[pastorteacher]

Maybe this is normal, I have a CDMA touch diamond with cellular south. running mighty rom right now, but the problem exists when running stock cellular south rom too. here's my problem: my data connection simply won't work after a few hours. I have to soft reset my phone for my data connection to work again. its not an issue with my signal strength. i mean, my data connection works after reseting the phone, its just a hassle having to reset it and wait to use it for 45 seconds or so.

any help would be appreciated.
